Hello eveyone! This is my first post to this forum and I hope someone can help me out. We recently adopeted our first dog - a 10 month old black lab mix named Oreo. He's fantastic! We have had him for 2 weeks now. Last week he went to the vet for Parvo, Leptospirosis, and kennel cough vaccinations and had a normal healthy checkup. (They did fecal testing which I'm assuming was negative and a heartworm test - they said they'd call if it was +, and have not). At the time, I was concerned that he had vomited twice late at night - once food, once food/liquid. The vet thought that it was the change in food, possibly excess acidity. He had previously been fed poorer quality food 3x per day. Now he's on Iams adult, 1 cup 2x/day (between 5 and 6 am, and between 5 and 6 pm). The vet said that if he had a good appetite and no other symptoms not to worry.
The new concern - yesterday afternoon around 3 he vomited a small amount of clear liquid (water?). And this afternoon we went for about an hour long walk, then half hour later (5 pm) he vomited frothy yellow fluid with a few buiscuit chunks in it. He ate a piece of grass on our walk today, but not much that I saw. He has NO lack of appetite (he actually vomited then sat next to where the food is kept) - I fed him around 6:30 this evening and he seems fine now (laying next to me gnawing on his nylabone!). Today was the only time he's vomited any time near exercise. Could this be a result of excess acid because it's been so long since his morning meal? He's scheduled to go to the vet on the 17th for booster shots - do you think this warrants a visit sooner?
